IMPROVEMENT IN LAMP ATTACHMENTS.

Specification forming part of Letters Patent No. 215,964, dated May 27, 1879; application filed February 8, 1879.

To all whom it may concern:

Be it known that I, L. W. PECK, of Minneapolis, Hennepin county, in the State of Minnesota, haveinvented an Improvementin Lamp Attachments, of which the followingis a specification.

Figure 1 of the drawings is a plan View, and Fig. 2 a diametrical cross-section. Fig. 3 shows my device applied to a lantern.

The object of the invention is to prevent combustible dust from entering the flame of lamps or lanterns and the invention consists in a peculiar construction by which this may be accomplished with better eti'ect than by the means at present known to the public.

In the drawings, D represents the hollow tube or box through which 1 cause the air to pass before it reaches the flame or combustion space of the lamp or lantern, and d a diaphragm which separates the tube or box into two parts or chambers. The air is first admitted through one or more apertures, a then caused to traverse nearly the whole length of the tube or box; next allowed to pass through the diaphragm at one or more holes, 0, and then forced to travel back the same distance before it is permitted to escape through one or more apertures, I). The efl'ect of this is to produce a deposit of thecombustible dust before the air reaches the 'flaine.

I am aware that it is not broadly new to cause the air to pass around angles and against friction-surfaces; but

What I claim is- In combination with a lamp or lantern, the tube or boX D, having the diaphragm d and apertures b ca, arranged as shown and described. a
